It\u2019s time to give these gadgets the praise they deserve and take a look at their (rather impressive) journey.\u00a0<\/span><\/p>\n Contents<\/p> Hearing aids are medical devices specially designed for people with hearing loss. As they can significantly improve the hearing of many individuals, they tend to be the go-to solution for those that are diagnosed as hard of hearing.<\/span><\/p>\n Although they can\u2019t restore normal hearing, hearing aids are fine-tuned to the wearer, boosting certain frequencies to aid hearing for each individual.<\/span><\/p>\n Hearing loss affects people far and wide, and with <\/span>one in eight people in the U.S. aged 12 or over experiencing hearing loss in both ears<\/span><\/a>, it\u2019s no wonder that even big-name celebrities such as Halle Berry and Jodie Foster are known to use hearing aids.<\/span><\/p>\n Those that struggle with their hearing can find their daily life increasingly difficult. Even simple interactions such as talking to a store assistant and asking for directions become tiresome. Sadly, this can lead to a sense of loneliness and place a strain on relationships with family and friends.<\/span><\/p>\n This makes it all the more startling that amongst all adults aged 70 and older with hearing loss who could benefit from hearing aids, <\/span>fewer than 30%<\/span><\/a> have ever used them.<\/span><\/p>\n <\/p>\n Unsurprisingly, the technology behind hearing aids went through many revisions before ending up as the device that we recognize today.\u00a0<\/span><\/p>\n The first literal hearing <\/span>aid <\/span><\/i>was called the \u2018ear trumpet\u2019 \u2013 a tubular device, designed to funnel sound waves into the ear. Unlike hearing aids today, these large funnels were made from materials such as wood, animal horns, snail shells, and sometimes silver or sheet metal.<\/span><\/p>\n Their use dates back to the 17th century, while <\/span>Jean Leurechon, the French priest and mathematician, is credited with the first mention of the instrument in his 1634 work <\/span>Recreations math\u00e9matiques.<\/span><\/i><\/p>\n Although the modern hearing aid and the ear trumpet seem worlds apart, it\u2019s tempting to draw some similarities.\u00a0<\/span><\/p>\n Interestingly, conical ear trumpets were custom-made by specialist instrument makers as bespoke pieces for each client. Although this isn\u2019t the case for hearing aids in 2020, it goes to show that there was some recognition of the need to personalize each device in a similar sense to how hearing aids are fitted to each individual, calibrated, and set to boost certain frequencies for maximum effectivity today.\u00a0<\/span><\/p>\n It certainly seems like they were onto something with this early invention!<\/span><\/p>\n Although ear trumpets may have looked aesthetically impressive, there was an undeniable need to move away from these passive amplification cones, and move on to something better.<\/span><\/p>\n It was in 1898 that the first portable hearing aid using a carbon transmitter, the Akouphone, was brought to life by Miller Reese Hutchison. Through the use of the carbon transmitter, an electric current could simply take a weak signal, and turn it into a strong signal.<\/span><\/p>\n Consisting of a separate microphone, amplifier, headphones, and battery (which didn\u2019t last very long), the device was clunky and difficult to use. Add a steep retail price and it\u2019s no wonder only a few people could use the Akouphone.<\/span><\/p>\n The lucrative prospects of hearing aids gained attention from large-scale manufacturers and engineers who wanted to improve the device, leading to the increasingly small, widely available devices used by millions around the world today.<\/span><\/p>\n Of course, this didn\u2019t just happen overnight. Numerous technologies have been tried and tested over the years.<\/span><\/p>\n In 1920, Naval engineer Earl Hanson patented the first vacuum-tube hearing aid named the Vactuphone. The device used the telephone transmitter to convert speech into electrical signals, to then be amplified through the receiver. It was so successful that vacuum tube hearing aids were available on the U.S. market from 1923.<\/span><\/p>\n Competition to develop the best miniaturization techniques aided development. Devices became smaller and smaller throughout the 1930s, were sold as wearable from 1936, and quickly gained popularity amongst the public.<\/span><\/p>\n At this time, the amplifier and batteries still needed to be worn around your neck and the microphone was hand-held (with its size proportional to your level of hearing loss!). This meant that conversations had to be had news reporter-style \u2013 quite a funny thought for hearing aid users today.\u00a0\u00a0<\/span><\/p>\n From 1948, transistors were on the scene. These replaced vacuum tubes as they were demonstrably superior on many accounts. They required less battery power, produced less distortion and heat than vacuum tubes, and importantly, were smaller.<\/span><\/p>\n However, manufacturers were so excited about the benefits transistors seemed to provide that they did not carry out adequate tests on their transistor hearing aids. They paid the price for their haste when devices seemed to die just a few weeks after a customer\u2019s purchase due to dampness stopping the transistor from working.<\/span><\/p>\n This led to the development of a protective coating and the silicon transistor, to combat problems caused by body heat.<\/span><\/p>\n The microprocessor was created in 1970, speeding up the journey towards the miniaturization of the hearing aid. Edgar Villchur, a researcher, even developed an analog multi-channel amplitude compression device that allowed audio signal to be separated into frequency bands. These were able to adjust the analog sound non-linearly; this is where certain sounds could be amplified less and other sounds could be amplified more.\u00a0<\/span><\/p>\n The 1970s saw the development of high-speed digital-array processors to be used with minicomputers, but it was only in 1982 that an all-digital, real-time, array processing hearing aid was developed at the City University of New York as a research tool for the exploration of digital signal processing. This rather bulky device consisted of a minicomputer and a digital array processor, as well as an FM transmitter and receiver.\u00a0<\/span><\/p>\n The 1980s ushered in the development of digital chips for high-speed digital signal processing. These enabled fast processing, but were too large and consumed too much power to be used in wearable hearing aids.<\/span><\/p>\n Over time, technology allowed these drawbacks to be reduced to practical levels for a digital hearing aid, most notably through the work of Engebretson, Morley, and Popelka at the <\/span>Central Institute for the Deaf (CID)<\/span><\/a>.<\/span><\/p>\n When 1987 rolled around, the Nicolet Corporation brought the first commercial digital hearing aid to market, and surprisingly, to little commercial success.<\/span><\/p>\n Nevertheless, Nicolet did prove one thing to the market \u2013 feasibility, and other companies took notice.<\/span><\/p>\n The race to develop viable digital hearing aids that would also be commercially successful had begun. Developments occurred at a rapid pace, and major hearing aid companies introduced hybrid instruments using analog amplifiers, filters, and limiters which were controlled digitally.<\/span><\/p>\n Now in the 21st century, we can see that hearing aids have come to be incredibly popular, and there\u2019s no doubt that their long history of technological modification and continued refinement is to thank for this. Many devices use modern technology such as Bluetooth connection and rechargeable batteries, offering convenience to the consumers.<\/span><\/p>\n Along with these advances, and the emergence of new options such as hearing amplifiers and PSAPs (Personal Sound Amplification Products) offers to the consumer a wide range of hearing device options with different capacities.\u00a0<\/span><\/p>\n Many of these devices are functionally versatile and have excellent efficiency, allowing for features such as effective ambient noise control, suppression, and isolation, and offer a much more aesthetically appealing (and less costly) alternative to hearing aids of the past.\u00a0<\/span><\/p>\n Although some claim devices such as hearing amplifiers and PSAPs pose a threat to the hearing aid market, this shouldn\u2019t be the case. Whilst they enhance your experience of environmental sounds and are incredibly useful in certain instances, they should <\/span>not<\/span><\/i> serve as replacements for hearing aids if you suffer from moderate to severe hearing loss.<\/span><\/p>\n At <\/span>Olive Union<\/span><\/a> we have a mission: to make hearing devices like glasses – i.e. removing the stigma around them and making them a personalized, normalized part of everyday life.<\/span><\/p>\n With recent technological developments, hearing enhancement devices are only becoming more effective and more widely used; the <\/span>Olive Smart Ear<\/span><\/a> is no exception.<\/span><\/p>\n Have you started to notice an inability to hear quieter sounds or hardness of hearing in noisy environments?<\/span><\/p>\n Customizable hearing enhancement could improve your quality of life, so why not try our smart hearing earbud?
